Two Magalia residents were arrested by the Butte County Sheriff's Office on Thursday after authorities allegedly discovered marijuana refining labs at properties in Concow and Magalia.

Rocio I. Buenrostro, 26, and Benjamin L. Pavan, 28, were taken into custody and are facing various marijuana-related charges, according to a press release from the Sheriff's Office.

As part of an ongoing investigation that started after a raid on Feb. 27 in Feather Falls, authorities served search warrants at residences on High Winds Road in Concow and in the 14700 block of Skyway in Magalia, according to the Sheriff's Office.

On Thursday, detectives from the Sheriff's Office Special Enforcement Unit and with the Butte Interagency Narcotics Task Force served the search warrant at the Concow property and allegedly located a butane honey oil marijuana refining lab, which included five extraction tubes, hot plates, vacuum pumps and vacuum chambers, and more than 200 empty butane cans and more than 80 full butane cans, the press release stated.

At the High Winds Road location, detectives also allegedly found two greenhouses with 162 marijuana plants and a motorcycle reportedly stolen out of Ventura County, according to the Sheriff's Office. The plants were reportedly destroyed. The motorcycle was taken to the Sheriff's Office to be returned to its owner.

After the raids, detectives arrested Pavan on suspicion of marijuana cultivation, possession of marijuana for sale, possession of concentrated cannabis, two counts of manufacturing a controlled substance, being armed in the commission of a felony, and maintaining a home where the manufacturing of honey oil and cultivation of marijuana was occurring, according to the press release.
